WATER-MOTO R.

SPECIFICATION forming part of Letters-Patent No. 431,156, dated July 1, 1890.

Application filed September 2, 1889. Serial No. 322,670. (No model.)

To all whom it may concern:

Be it known that I, HENRY E. TRUMBLE, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful \Vater- Motor, of which the following is a specification.

This invention relates to that class of watermotors in which the piston consists of two plates end to end and jointedly connected together, and in which the end of one of the plates is pivoted at a fixed point and the free end of the other plate acts as a cut-off valve at the induction-port.

The object of the invention consists in a construction whereby the end of the piston which serves as the cut-off is controlled and timed in its movement independently of the action of the water at the induction-port.

Other objects in relation to the inductionport and exhaust-ports will appear in the following description and claims.

In the drawings forming a part of this specification, Figure 1 is a side elevation with one of the walls of the flume removed and parts broken away; Fig. 2, an end elevation looking from a point at the left in Fig. 1. Fig. 3 is an end elevation looking from a point at the right of Fig. 1. Fig. 4 is a section of the left-hand end of Fig. 1 on line 3 3 in Fig. 2, looking from a point above. Fig. 5 is a sectional View of the right-hand end of Fig. 1 on line 4 4 in Fig. 3, looking from a point above. Fig. 6 shows lettered details from Fig. 1, and Fig. '7 shows enlarged letter details at the left in Fig. 1.

Referring to the lettered and numeral parts of the drawings, A is an elongated rectangular fiume, in which the piston is located and through which the water flows. The piston consists of two plates G and B end to end and jointly connected together, as in Fig. 1, one end of the rear plate B being pivoted in the flume at 0', Figs. 1 and 5.

At 1 is a piston-rod attached to the piston at one end and by a pitman F to the crankdisk 2 of an ordinary power-shaft, said pitman being pivoted to the piston-rod at 0, said piston-rod of course passing through the wall of the fiume.

3 is a centrally-pivoted lever, and c is a rod pivotally attached at the upper end to one end of said lever 3 and at the lower end, at m, to the free end of the plate G of the piston.

The object of this construction is explained as follows: When the piston is in the position shown in Fig. 1, the rear end of the lever 3 rests against the projection 00 on piston-rod 1,and thus the front end of the plate G is raised to the angle shown in Fig. 1. hen in this position, the water which flowed through the fiuine above the piston is shut off by the gate a, with which the end of the Y plate G'comes in contact, and the water then flows through the flume beneath the piston. The gates a are held out to place by springs, as at the lower left-hand corner in Fig. 1.

At i is a bar adapted to yield against the springs 25, said springs being between the ends of said bare and the end standard R of the flume A, as in Figs. 1 and 7. Attached adjustably to bar 1' are castings 6, held by set screw at 4. These castings e are provided with spring-plates n, and the end of the plate G of the piston comes in contact with said plates n during the reciprocating movements of the piston. The object of having the bar 'iyield against it spring-resistanceis to accommodate the lengthening and shortening of the jointed piston when it comes in contact with the spring-plates n of the castings e. Said castings are provided with shoulders'o, against which the end of the plate G catches for the purpose of holding said plate G of the piston from tilting too soon.

In Fig; 1 the water flowing through the in duction-port beneath the piston will raise the latter upward toa position opposite to that shown in said figure, and when the joint of the piston has reached the upper side of the fiunie the free end of the plate G will be released from the shoulder 5 of the upper casting 6, and said plate G will tilt against the lower gate a and will be held in a posit-ion opposite to that in Fig. 1 against the shoulder 5 of the lower casting e through the medium of the lever 3, the rear end of which lever is i carried upward by the projection S 011 the pis- IOO rear end of the flume. The plate G of the piston, if left entirely free at the outer end, would be automatically tilted by the action of the water as the central joint of the piston moves up and down, thus serving as a cut-off; but said plate might be liable to tilt before the piston-rod had completed its stroke, and to obviate this difficulty I employ the stops 6 before described. These stops are provided with a set-screw Z for throwing the end of the springs n in or out, and thus ad lower end at u. The walking-beam is fulcrumed at w and is actuated by the eccentric 1 (Shown in Fig. 6.) Then the piston-rod moves down, the gate D moves up. and opens the exhaust-port above the end of the piston and closes the port below. This position of the piston and gateD is shown in Figs. 1 and 3, in which the water is supposed to be exhausting through the upper exhaust-port and entering the lower ind u ction-port between the lower gate a and theend of the piston, Fig. 2,

and of course when the piston-rod moves upward the reverse action takes place as to the exhaustion and induction of the water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination of the flume, the piston composed of the two plates end to end and jointedly attached to each other, the pistonrod and power-shaft, the pitman pivotally connecting said shaft and piston-rod, said piston-rod being providedwith the projections, the centrally-pivoted lever which is operated by the contact of the end of said lever with the projections, a rod pivoted at the upper end to the other end of said lever and at the lower end to the front end of the piston, and the yielding stops, against which the free end of the piston catches, substantially as set forth.

2. In a motor, the combination of the flume, the jointed piston, as described, a power-shaft, the piston-rod, the walking-beam operated by said shaft, the exhaust-gate, and the rod connected to said gate and to the end of the walking-beam, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.

HENRY E. TRUMBLE.
